Size & Weight

Lithium batteries with different capacities require varying amounts of LifePO4 battery cells depending on the capacity, which is the case for the 100Ah and 200Ah Ampere Time batteries, which differ in size & weight.

100Ah Ampere Time Battery

The 100Ah Ampere Time Battery has a compact size of 13 x 6.82 x 8.48 in. and a relatively lightweight of 25.35 lbs., which is lighter than batteries with similar capacity. Comparing the size and weight as they relate to capacity, the 100Ah Ampere Time battery is ideal for stationary applications and others that might require manually transporting the battery.

200Ah Ampere Time Battery

The 200Ah Ampere Time battery has a size of 20.5 x 9.37 x 8.54 in. and a weight of 46.07 lbs. While it has twice the capacity of 100Ah Ampere Time Battery, it is only 82% heavier, but it has more than twice the size. Since this battery is heavier and bulkier, we recommend it for stationary applications or in-home solar power systems, personal vehicles, wheelchairs, or marine applications.

Casing & IP rating

While both batteries have a different weight and size, they share a similar high-quality casing that is durable, robust, and includes handles for transportation. The casing is ABS material, which is resistant to shocks and vibrations. Both batteries have 16mm-M8 terminals installed and are versatile for many applications.

With a casing manufactured with the highest standards, both batteries have a high Ingress Protection (IP) rating of IP65. They are completely sealed against dust particles, protected against small splashing or dripping of water, and withstand water jets with a nozzle of 6.3 mm or less.

Charge/discharge current

Both batteries can deliver high peak currents of 280A for five seconds and continuously discharge at a maximum current of 100A, meaning the 100Ah Ampere Time battery is ideal for a 1C C-rate and the 200Ah battery for a 0.5C C-rate.

You can charge both batteries at a 0.2C C-rate, meaning that you can charge the 100Ah battery at 20A while the 200Ah Ampere Time Battery at 40A.

Depth of Discharge (DOD)

Ampere Time has engineered quality LiFePO4 batteries that can be discharged at a 100% DOD, allowing you to use the full capacity of the batteries.

Even though they can withstand a 100% DOD, at 10% capacity, they read a voltage of 12.8V, and at 1%, they read 10.8V, which is why we recommend using a maximum 90% DOD, and avoiding discharging them beyond 99% DOD since it can damage the battery.

Expected life cycles

The 100Ah and 200Ah Ampere Time batteries are designed to deliver 4,000 – 8,000 cycles, depending on the DOD used. The average lifespan for both batteries is 10 years.

Working temperature

Both batteries can also work at the same temperatures. Ampere Time batteries can discharge from -4º F to 140º F and should only be charged at a temperature range of 32º F – 122º F. For storing the batteries, you should ensure a temperature range of 14º F – 122º F.

Supported parallel/series connections

Ampere Time batteries allow for up to 4 batteries to be connected in series or up to 4 batteries to connect in parallel. If you want to perform a parallel/series connection, you can plug 2 sets of 4 batteries in series, connected in parallel with each other.
